Terminal structure and electronic component

Abstract

A plurality of first terminal pins are placed side by side in a first direction. A plurality of second terminal pins are placed to extend in parallel with the plurality of first terminal pins. The plurality of first terminal pins and the plurality of second terminal pins include an inside face facing each other, an outside face opposite to the inside face, and side faces connecting the inside face and the outside face. At least one of the side faces includes a first portion having a relatively rough surface, and a second portion having a relatively fine surface and having approximately the same roughness as the inside face and the outside face.

 the first terminal pin includes a plurality of first terminal pins and the second terminal pin includes a plurality of second terminal pins; and   the plurality of first terminal pins and the plurality of second terminal pins are respectively placed in a first direction to extend in parallel with each other.   
     
     
         3 . The terminal structure according to  claim 1 , wherein the first portion is closer to a side on which the first terminal pin and the second terminal pin are adjacent to each other than the second portion. 
     
     
         4 . The terminal structure according to  claim 1 , wherein, when viewed in a direction in which the first terminal pin and the second terminal pin extend, a length of the inside face is different from a length of the outside face. 
     
     
         5 . The terminal structure according to  claim 4 , wherein a portion in which a longer side of the inside face and the outside face is connected to each of the side faces has a round chamfered shape. 
     
     
         6 . An electronic component comprising:
 the terminal structure according to  claim 1 ;   a circuit board on which a first end of the first terminal pin and the second terminal pin is mounted, the first end being in an extension direction in which the first terminal pin and the second terminal pin extend; and   an insulating resin covering the circuit board and covering an entirety of the first terminal pin and the second terminal pin except for a second end of the first terminal pin and the second terminal pin in the extension direction.   
     
     
         7 . The terminal structure according to  claim 2 , wherein the first portion is closer to a side on which the first terminal pin and the second terminal pin are adjacent to each other than the second portion. 
     
     
         8 . The terminal structure according to  claim 2 , wherein, when viewed in a direction in which the first terminal pin and the second terminal pin extend, a length of the inside face is different from a length of the outside face. 
     
     
         9 . The terminal structure according to  claim 3 , wherein, when viewed in a direction in which the first terminal pin and the second terminal pin extend, a length of the inside face is different from a length of the outside face. 
     
     
         10 . An electronic component comprising:
 the terminal structure according to  claim 2 ;   a circuit board on which a first end of the first terminal pin and the second terminal pin is mounted, the first end being in an extension direction in which the first terminal pin and the second terminal pin extend; and   
       an insulating resin covering the circuit board and covering an entirety of the first terminal pin and the second terminal pin except for a second end of the first terminal pin and the second terminal pin in the extension direction. 
     
     
         11 . An electronic component comprising:
 the terminal structure according to  claim 3 ;   a circuit board on which a first end of the first terminal pin and the second terminal pin is mounted, the first end being in an extension direction in which the first terminal pin and the second terminal pin extend; and
